Labor deputy leader Richard Marles won't attend parliament in Canberra next week as he awaits the results of a COVID-19 test.

The Victorian MP said on Thursday afternoon he had been made aware of having been at a Tier 1 exposure site on October 7.

"As a result, I have followed the health advice, have been tested and am now isolating until further notice," he said in a statement.

"Unfortunately this means I will not be able to attend parliament next week."

He said it was important all Australians followed health advice and played their part to keep the community safe.
