Melbourne to get 100-level apartment tower

A 100-level apartment tower is set to be built in Melbourne, giving the city the tallest building to the roofline in the southern hemisphere.

The tower, Australia 108, is one of three new skyscrapers to get state government approval for central Melbourne.

At a height of 319m above the ground, it will surpass Melbourne's Eureka tower by 22 metres.

"It'll be a large addition to Melbourne's skyline," Planning Minister Matthew Guy told reporters on Thursday.

He said it would also surpass the Q1 Gold Coast tower, whose spire reaches 323 metres.

"The top of Q1 is about 275m, so it is by far and away the tallest building to the roofline anywhere in Australia."

Another 75-storey apartment tower has been approved at 452 Elizabeth Street, along with a 54-storey building at 90 Queensbridge Street, Southbank.

Mr Guy says the new skyscrapers, involving investment of more than $830 million, will house 4000 people and generate 5800 construction jobs.
