Western Australia is welcoming back travellers from NSW and Victoria without the need to quarantine for the first time in almost nine months.

Under changes that came into effect overnight, the states have been reclassified as "very low risk", removing the requirement to self-isolate for 14 days.

It leaves South Australia as the only state still subject to travel restrictions.

SA travellers will no longer require exemptions to enter WA as of Friday, although they will still need to enter self-quarantine.

Queensland will open up to Adelaide from Saturday as long as there are no unlinked cases in coming days.

The decision by WA to proceed with reopening is significant for those separated from loved ones with Christmas around the corner.

But Premier Mark McGowan is warning the hard border could return "in a heartbeat" if circumstances change, revealing the state will retain police officers at border checkpoints at Eucla and Kununurra and at the airport despite the easing of controls.

China stops imports from another Aust beef plant.

China says it has suspended imports of beef from Australia's Meramist Pty Ltd, the sixth supplier to face such a move in a country that is one of China's main meat suppliers.

China, which did not say why it took the latest decision, has already banned imports from five other Australian beef suppliers this year, citing reasons that have included issues with labelling and health certificates.

Australia's ties with top trade partner China, already strained, significantly deteriorated after Canberra called for an inquiry into the origins of the coronavirus.

China's exorbitant tariffs on Australian wine are threatening to wipe out small, independent winemakers, industry advocates say.

With many small growers and wineries impacted by last summer's bushfires and the pandemic, the tariff hike of up to 212 per cent could be the final nail in the coffin.

A survey of 65 independent wineries in South Australia found almost half were worried about the future of their business, compared to only 25 per cent last year.

Swimmer Shayna Jack's doping ban to be appealed.

Swimmer Shayna Jack's two-year doping ban is being appealed by Sport Integrity Australia (SIA).

SIA on Monday lodged a statement of appeal with the Court of Arbitration for Sport (CAS), which suspended Jack for two years after she tested positive to the banned substance Ligandrol.

SIA chief executive David Sharpe says the appeal to CAS' appeals division is based on a need for clarity regarding anti-doping legal principles.

"Sport Integrity Australia will always act to ensure a level playing field for athletes," Sharpe said on Monday.

"In order to protect athletes and sporting competitions, we must have clarity and consistency in the application of the World Anti-Doping Code."

Sharpe declined to elaborate on the specifics of the appeal, citing confidentiality. A hearing date has not been set.

Jack was initially banned for four years after testing positive to Ligandrol on June 26 last year, almost three weeks before the world swim titles in South Korea.

The 22-year-old Queenslander appealed her ban to CAS which early last month reduced her suspension to two years, finding Jack did not knowingly ingest the substance.

Wage theft to be made criminal offence.

Wage theft will be made a federal criminal offence with beefed up civil penalties to crack down on bosses who underpay workers.

The Morrison government's industrial relations omnibus bill will include a strengthened compliance regime after years of underpayment scandals.

Industrial Relations Minister Christian Porter said it would be the first time a commonwealth wage theft law exists.

Government’s IR bill proposes new criminal offence for the “most egregious examples of genuine wage theft”. Would carry a max penalty of up to 4 years jail or a $1.1m penalty – or both – for individuals, and up to $5.55m for a body corporate. @australian https://t.co/kMft0or1G7

He said last week's revelations that some blueberry workers were paid as little as $3 an hour on NSW farms showed why the government was acting.

The new offence will carry a maximum penalty of four years' jail and fines of up to $1.1 million for individuals and $5.5 million for companies.

It will apply to national system employers that deliberately underpay one or more workers.

People convicted of wage theft would be disqualified from managing companies for five years.

Breakdancing, surfing, skateboarding and sports climbing have won a spot in the 2024 Paris Olympics after the International Olympic Committee ratified their inclusion, IOC President Thomas Bach says.

Paris Games organisers have said they want to deliver a programme that is in keeping with the times and will attract a new and younger audience.

Under new IOC rules first introduced for the Tokyo Games, Olympic host cities can hand-pick sports and propose them for inclusion in those Games if they are popular in that country and add to the Games' appeal.
