Pat Conroy will attend the Australia-UK defence industry dialogue alongside the British Defence Readiness and Industry Minister Luke Pollard.
It's the first iteration of the ongoing exchange since 2018, with the two nations deciding to restart talks at the industry ministers' level in 2025.
The two nations alongside the United States form the AUKUS agreement, under which Australia will acquire nuclear-powered submarines, at first off-the-shelf from Washington as a new class of vessel is developed by all three partners.
Mr Conroy will tour sites where the SSN-AUKUS class submarines are being built to observe progress, as well as meet with local defence industry partners.
This includes those critical to building Australia's nuclear-skilled workforce as it prepares to acquire and man nuclear submarines for the first time.
"The Australia-UK defence industry dialogue is an opportunity to discuss deeper defence industry collaboration and ways we can collectively strengthen our defence capability," Mr Conroy said.
Labor is facing calls from the opposition to boost defence spending to ensure AUKUS, which is set to cost in excess of $350 billion over coming decades, doesn't cannibalise the rest of the defence force.
The federal government has defended its defence spending, saying it has pumped more money into national security than the coalition.
Defence Minister Richard Marles and Mr Conroy announced the signing of two contracts for heavy and medium landing craft on Friday.
Some $4 billion is being pumped into the army's heavy landing craft fleet, under which eight will be built in Western Australia.
They will be capable of transporting more than 500 tonnes of long-range weapons and other units by sea.
A $1 billion contract with Austral will result in 18 medium landing craft being handed over to the military.
