Aboriginal flag to fly on Melbourne bridge

But when NAIDOC week ends on Sunday, the Aboriginal flag will remain in place on the bridge, replacing Victoria's state flag.

"The West Gate Bridge is one of our most visible landmarks. Now, the thousands of motorists who use the bridge every day can view the Aboriginal flag flying proudly above our city," Victoria's Roads and Road Safety Minister Ben Carroll said.

The Victorian government is exploring ways to fly the Torres Strait Islander and Victorian state flags alongside the Aboriginal and Australian flags.

It follows a similar move by the NSW government to permanently fly the Aboriginal flag on the Sydney Harbour Bridge at a cost of $25 million.
