Labor claims Aukus nuclear waste dumping issue just a Greens scare campaign

The Albanese government has bowed to pressure to close an Aukus loophole, insisting that the newly revealed changes will ensure Australia will not become a dumping ground for nuclear waste from US and UK submarines.

The Greens argued the government’s latest amendments did not go far enough and it was becoming increasingly clear the Aukus security pact was “sinking”.

But Labor MPs later told the parliament Australia would not become “a dumping ground for nuclear waste for other countries” and argued such claims were part of “a scare campaign”.

The legislation before the Australian parliament covers the way the country’s nuclear-powered submarine program will be regulated. It includes the creation of a new statutory agency, the Australian Naval Nuclear Power Safety Regulator.

The bill – in its original form – talked about “managing, storing or disposing of radioactive waste from an Aukus submarine”, which it defined broadly as Australian, UK or US submarines.

This prompted concerns from critics that the bill could pave the way for Australia to eventually store nuclear waste from other countries, regardless of a political commitment from the incumbent government not to do so.

In May, a Labor-chaired inquiry called for a legislative safeguard to specifically rule out accepting high-level nuclear waste from the US and the UK.

New amendments circulated by the government on Wednesday include a “prohibition on storage and disposal of spent nuclear fuel that is not from an Australian submarine”.

The wording says the regulator “must not issue a licence” for the storage or disposal in Australia “of spent nuclear fuel that is not from an Australian submarine”.

The government is also amending the bill to prevent appearances of conflicts of interest at the new naval nuclear safety regulator.

The legislation will ensure anyone who has worked in the Australian defence force or the Department of Defence in the previous 12 months cannot be appointed to be the director general or deputy of the new regulator.

The defence minister, Richard Marles, said the amendments would “reaffirm the government’s already-established commitment that Australia will not be responsible for the storage or disposal of high-level radioactive waste from the US, UK or other countries”.

He said the government would “continue to build the foundations to safely and securely build, maintain and operate conventionally armed, nuclear-powered submarines”.

Greens say changes ‘far from clear’

But the Greens defence spokesperson, David Shoebridge, said the amendments were “far from clear”.

“The Albanese Labor government tried to sneak through a loophole that would allow the UK and US to dump their nuclear waste in Australia,” Shoebridge said.

“We called the government out and people around Australia pushed back, now Albanese is quickly putting through a half-measure to shut everyone up.”

Shoebridge said the amendment did not specifically mention “high-level radioactive waste” and it “still allows the US and UK to dump intermediate-level waste, and Australian high-level waste, anywhere in Australia”.

“Everyone can see Aukus is sinking,” he said.

Matt Thistlethwaite, an assistant minister, said Australia would “not manage, store or dispose of spent nuclear fuel from the US or the UK submarines”.

He told the parliament’s federation chamber that the government’s new amendments were intended to “put the matter beyond doubt”.

A fellow Labor MP, Rob Mitchell, said: “We will not be, as some have suggested, a dumping ground for nuclear waste for other countries. And it’s important that we put that scare campaign to bed very quickly and very clearly.”

The Coalition frontbencher Barnaby Joyce said Aukus was “fundamental” to defending Australia at a time when totalitarianism was on the rise and democracy was on the wane around the world.

“We need a defence force, because without a defence force, you don’t have to worry about Indigenous policy, because there will be no Indigenous policy, [because] you won’t have a nation,” Joyce told the chamber.

Joyce said Australia had “a massive step to take” to defend the nation “and we’d better do it in a big, big hurry”.
