Pro-Russia protesters have marched on the prime minister’s house over the decision to block a new Russian embassy build near Parliament House.

Roughly 20 protesters waving Russian and Australian flags, posters of Russian president Vladimir Putin and placards mocking Prime Minister Anthony Albanese rallied at Kirribilli House in Sydney, calling on the government to keep its hands off the Russian embassy.

On June 15 federal parliament swiftly passed laws to terminate the lease for a new Russian embassy within 500 metres of Parliament House, following advice about potential security risks.

Protest placards read, “Who is Albo”, and “deep state lap dog”, while others wore t-shirts sporting the Russian pro-military Z symbol.

Russia has launched a High Court bid to have the laws terminating their lease on the site overturned and a hearing is listed for Monday in Canberra.

Earlier on Saturday, Mr Albanese said he was confident the court action would be resolved in the government’s favour.

“I’m very confident that it will be resolved appropriately and in accordance with Australian law,” he said.

“We’re very confident about our legal position.”

Australian Federal Police are monitoring a Russian diplomat squatting in a shed on the proposed site, but have been unable to arrest him due to diplomatic immunity.
