The Temporary
  Skill Shortage (subclass 482) visa (TSS visa) came into effect in March
  2018, replacing the Temporary
  Work (Skilled) (subclass 457) visa. It is intended to help meet skills
  shortages in the Australian labour market while ensuring protection of local
  jobs, wages and conditions. It allows employers to sponsor overseas workers
  where no Australian workers are available. Visa holders can stay in Australia
  up to 2–5 years, as long as they continue to work for their employer. There is
  no cap on the number of visas which can be granted in any year. 
There are 3 main streams for the visa: Short-term,
  Medium-term and Labour Agreement. The table below summarises the visa settings
  for applicants and employers, with further explanations given in the discussion
  that follows. These settings are current as at September 2022. 
Employer requirements
Employers must meet a range of requirements before they
  are able to sponsor migrant workers. 
Employers must be approved as a standard
  business sponsor, which requires paying a fee, demonstrating they are
  running a legally established and operating business, and having ‘a strong
  record of, or a demonstrated commitment to, employing local labour’. To
  maintain their status, employers must continue to meet sponsorship
  obligations. 
Employers must undertake labour
  market testing to demonstrate they cannot find an Australian resident to do
  the work. Labour market testing generally requires advertising the position for
  at least 4 weeks within the 4 month period immediately prior to lodging the
  nomination application (part of the visa application process). The advertising
  must meet certain requirements, including that it be via methods or media with
  national reach in addition to being on the Workforce
  Australia website. 
Labour market testing applies to labour agreements (see
  below), but there are flexible arrangements in place for some agreements, for
  example, a longer advertising window for jobs in certain regional areas. 
There are some exemptions to labour market testing
  requirements where an International Trade Obligation applies. There are also
  alternative requirements in place in specific cases, including if the salary
  paid will be over $250,000; for a small number of specified professions; or for
  intra-corporate transfers.
Employers must pay the employee at least the annual
  market salary rate and above the
  Temporary Income Skilled Migration Threshold (TSMIT, set at $53,900).
The Skilling Australians Fund levy
Employers sponsoring a visa applicant must pay the Skilling Australians
  Fund levy. The fund aims to ensure that businesses that sponsor migrant
  workers are also benefitting Australian workers. The levy must be paid for each
  worker, as noted in the table above (see the Department of Home Affairs webpage
  on costs
  of sponsoring for further details).
The fund supports projects to provide training
  opportunities including apprenticeships and traineeships, pre-apprenticeships
  and pre-traineeships, and other employment-related training opportunities (see
  the Skilling Australians Fund fact
  sheet for further information). 
The Skilled Occupation List
The vacancy the employer wishes to fill must be for an
  occupation on the Skilled
  Occupation List. The list specifies occupations for eligibility for a range
  of skilled visas (permanent and temporary, including the TSS), and is aimed at
  identifying occupations where there are skills gaps in the Australian labour
  market which would be appropriate to fill using skilled migration. The list is
  revised periodically by the National
  Skills Commission. 
The combined Skilled Occupation List is made up of 3 main
  lists: the Short-term Skilled Occupation List (STSOL), the Medium and Long-term
  Strategic Skills List (MLTSSL), and the Regional Occupation List (ROL). There
  is also currently a Priority
  Migration Skilled Occupation List (PMSOL), introduced as a temporary
  measure in September 2020 in response to the COVID‑19 pandemic to facilitate
  the entry of workers in critical sectors.
Applicants for the Short-term
  stream of the TSS visa must have an occupation on either the STSOL or the
  PMSOL. Applicants for the Medium-term
  stream must have an occupation on either the MLTSSL or the PMSOL. The lists
  do not apply to applicants for the Labour
  Agreement stream, but applicants must meet the requirements to be sponsored
  by an employer with a labour agreement in place.  
Labour Agreements
If an employer cannot meet their skills needs through
  Australian workers or existing skilled visa programs, they may be able to use a labour
  agreement. Labour agreements are negotiated between employers (or a state,
  territory or regional authority) and the Department of Home Affairs
  (representing the Australian Government). There is a range of types of labour
  agreements, covering designated regions, industries (largely in the
  agricultural sector), specific large projects or specific companies. The
  agreements function as a contract, setting out terms that employers must comply
  with in addition to sponsorship obligations similar to the standard business
  sponsorship obligations (see above). 
Labour agreements use existing visas, including the TSS
  (and permanent skilled visas), but may provide concessions in relation to the
  standard requirements or occupations for those visas. The annual market salary
  rate still applies, so that a worker under a labour agreement should not be
  paid less than an equivalent Australian worker, even if the labour agreement
  allows them to be paid below the TSMIT. 
Employment conditions and
  entitlements
Employers of TSS visa holders must ensure that the terms
  and conditions of employment are no less favourable than those they provide to
  Australian citizens or permanent residents performing equivalent work in their
  workplace. This includes minimum wages, hours of work and leave entitlements. 
The Fair Work Ombudsman website has information on the workplace
  rights and entitlements for 482 and 457 visa holders and a page for
  migrant workers on how to access help regarding unfair workplace treatment.
Requirements for applicants and
  visa conditions
TSS visa applicants must be nominated by an approved
  sponsor, prove they have the required skills and experience to meet the
  relevant occupation as listed on the Skilled Occupation List (such as via a skills
  assessment if required), and meet English language requirements. All visa
  applicants must generally comply with standard visa requirements including
  health, character and security checks.
TSS visa holders must work only for their sponsor or
  associated entity, and only in the occupation they were nominated for, unless exempt.
  If their employment ends, they have 60 days to find a new employer to sponsor
  them, or they must leave Australia. 
TSS visa holders (primary visa holders) may bring
  dependent family members (secondary visa holders) to Australia with them. These
  family members can live, study and work in Australia, with no restriction on
  the kind of work they can do. 
TSS visa holders, like other temporary
  visa holders, are generally not entitled to social security benefits or Medicare,
  and must have adequate health insurance. 
The employer may sponsor the worker for further TSS visas
  after the time limit on the initial visa. The employer may also sponsor the TSS
  visa holder for permanent residence through the Employer
  Nomination Scheme (subclass 186) visa, if the employee has been working for
  them for at least 3 years and the occupation is on the Medium and Long-term
  Strategic Skills List or the Regional Occupation List. The Short-term stream of
  the TSS visa usually allows only one subsequent TSS application and no pathway
  to permanent residence; however, for
  a 2-year period from 1 July 2022, this pathway is open to Short-term stream
  applicants.
Medium-term and Labour Agreement TSS visa holders are also
  able to apply for other kinds of visas if they meet the criteria. 
Visa trends
The following chart shows trends in TSS and subclass 457
  visas granted and visa holders in Australia over the past 10 years (‘snapshot’
  figures are as at 30 June for each year). The figures are for primary visa
  holders only. 
The effects of the COVID-19 pandemic over the past 3
  financial years are evident. The dip in 2017–18 possibly reflects the changeover
  between the subclass 457 and the TSS visas; however, see also this 2018 Parliamentary
  Library FlagPost, which noted a number of possible factors influencing trends
  in subclass 457 visa applications.

Further resources
Home Affairs visa data and reports
The Department of Home Affairs issues quarterly statistical Temporary resident
  (skilled) reports on
  its website, including a detailed report and a separate 3-page summary. Pivot
  table data is available at data.gov.au. These reports cover the TSS and its
  predecessor, the subclass 457 visa.
Recent parliamentary inquiries
A number of recent parliamentary
  inquiries have examined the TSS visa as part of their remit. The reports cover
  considerations, stakeholder views and recommendations on settings, including
  the TSMIT, labour market testing, the Skilling Australians Fund levy, the
  Skilled Occupation List, exploitation of migrant workers and pathways to
  permanent residence.
The Select
  Committee on Temporary Migration tabled its report in September 2021. The
  report considers the TSS visa in addition to other temporary visas (including
  student, working holiday, seasonal and temporary graduate visas). It also discusses
  challenges in addressing skills shortages and labour market gaps.
Chapter 4 discusses workplace exploitation of temporary visa
  holders, including a summary of previous inquiries, the Migrant Workers’
  Taskforce, the role of the Fair Work Ombudsman, and the Migration
  Amendment (Protecting Migrants Workers) Bill 2021, which was at that time
  released as an exposure draft. The Bill lapsed at the dissolution of the 46th
  Parliament. For more on the Bill, see the Library’s Bills
  Digest.
The Inquiry
  into Australia’s skilled migration program focused on permanent skilled
  visas but included consideration of the TSS visa. Its final
  report was tabled in August 2021. 
The Legal and Constitutional Affairs References Committee
  tabled its report on the Inquiry
  into the effectiveness of the current temporary skilled visa system in
  targeting genuine skills shortage in April 2019. The report looks primarily
  at the TSS visa and the previous subclass 457 visa but also notes other
  temporary work visas (subclasses 400, 403 and 408). It considered a number of
  issues raised in later (and earlier) reports, but at that point the TSS visa had
  not been in place very long, so the committee recommended further monitoring.
