A hundred people are expected to line up before the My Kids Market doors open to be the first to get their hands on pre-loved children's goods today.
The market at Punchbowl Christian Centre runs from 9am until 12pm, with more than 40 stall holders selling pre-loved children's goods and new items.
Organiser Ursula Donati founded the market in 2017 and said it was very popular and had a positive environmental message selling pre-loved things.
"We have between 400 to 500 people every market.
"From 8.30am people start lining up outside...so there is 100 people lining up every morning before the market starts," she said.
It is $3 entry, children are free, and there is rock painting and other activities on offer to children from zero to ten.
