Cordeaux Heights mum Leah Karlis has called for a ban on council kerbside rubbish pick-ups, claiming the garbage piles attract scavengers and thieves.
Several near-new scooters and a bike were stolen from the woman's front lawn, along with a bike parked on a neighbouring property in the normally quiet Silvertop Parade cul-de-sac on Sunday.
Ms Karlis believes a neighbour's front yard rubbish pile had attracted strangers to the area, keen to pick through the garbage - and perhaps pocket some new items along the way.
"All the kids' gear was pretty new so it's not like it could be mistaken for rubbish, the [thieves] knew what they were doing, it was just opportunistic," she said.
"We saw some cars driving past, looking to see what was in the pile of rubbish and what they could pick up - it just encourages people who wouldn't normally be in the area to visit.
"The sooner they ban the [pick-ups], the better."
The theft has left residents in the street devastated, particularly the Karlises' six-year-old son Kieran.
He wrote a letter to the Mercury, saying he was "sad" that someone would take things from their yard.
Mrs Karlis said the children had abandoned their bikes and scooters on the lawn over the weekend - a regular occurrence in the kid-filled street.
When they returned from a dip in a nearby pool, they discovered the gear had disappeared.
"All that was left was the helmets, it was very upsetting," Mrs Karlis said.
"It's awful to think the kids can't just leave their bikes outside; it's not unusual for 10 or so bikes to be left out and we just won't be able to do that any more," she said.
The incident comes as Wollongong City Council continues to review its on-call household clean-up service.
A council spokesman said on Tuesday that households must place suitable materials for pick-up outside their home no earlier than the day before the clean-up is booked.
"This will help deter people scavenging items from the material outside a home and help stop other people from adding unsolicited materials to the pile," he said.
Lord Mayor Gordon Bradbery called for a review of the service on February 24.
The council requested the review be completed by June.
