At least 15 testing sites in Melbourne were temporarily closed at 9am after reaching capacity, including the Bourke Street walk-in and Albert Park drive-through.

Victorian MP Ben Carroll said Acting Premier James Merlino and Health Minister Martin Foley were working “around the clock” to find solutions to cope with the influx of people needing tests before Christmas.

“They are looking at more resources in terms of extending hours,” he said on Monday.

The state government has increased testing capacity by about 55 per cent since October, with about 260 sites operating across Victoria.

On Monday night, Melbourne Lord Mayor Sally Capp announced a testing site would open at Town Hall from 10am Tuesday to January 24, in response to demand.
