The markets have been restricted in their trade throughout the COVID lockdown - first only fresh food, then plants, then coffee and then takeaway food.

But its now back to offering arguably what draws the biggest crowds - its second hand goods, its trash and treasure, from clothes to books; tools to furniture.

"This is the first one where we're right back," Leo said.

"We had 50 stalls last week. We hope to have 150 stalls this week."

The lockdown was the first time the markets had been disrupted in their 47-year history.

They operate from the car park behind the Jamison Centre, in Bowman Street, stall holders hiring a car space for $20.

Bookings are now online at: trashandtreasuremarketjamison.com.au

The club's market director Linda Baldwin said the markets had since 1974 raised more than $7 million for local causes.

Entry to shop at the market is by donation.

Rotary Club of Belconnen volunteers, take the entry donations and clean up afterwards.

"Part of your membership is that you volunteer here at Trash and Treasure," Rotarian Judy Perry said.

They are excited to welcome everyone back, saying stallholders bonded during the pandemic.

"Before the pandemic, there was a lot of narkiness between the stallholders - 'You're in my spot' - that kind of thing," Ms Perry said.

"Now, they're so cooperative. It's so lovely. And we know all their names, because we've had to register them. So we can call them by name and it's nice."

Mr Farrelly agreed.

"COVID caused us to change but it's also changed all of the relationships which has been really one of the best things to come out of it all," he said.

The Trash and Treasure Market Jamison is Sunday from 7am to 12.30pm.
