"We're doing what we can to put the word out there," Ms Crow said. "It's has been a bit of a kick in the guts, but we're trying to stay positive. Our centre is here for the community and, if people can't respect that then we need to do everything possible to protect it."
The centre's woes began in December when vandals damaged playground equipment, toys and the outdoor plastic curtains used as shelter from bad weather, which were slashed with a knife.
A few short months later, a burglar attempted to break in, removing pins in the building's front door.
"We're gutted -- it's really disappointing," Ms Crow said.
"There's nothing of value people can take, but it has value to us and it's a huge cost to replace.
"Why would someone target a charitable organisation that works with children? It doesn't make sense."
Parents have also reported seeing a person squatting outside the centre, who has taken off over the fence when approached.
Adding to the parents' headache is incessant littering, likely from teens hanging out at Howard Booth Park -- anything from cigarette butts to bags of old nappies opened and scattered on the grass.
"It's pretty yuck," Ms Crow said.
"We're having to go on rubbish duty, just like we had to do in high school -- and that's time we could be spending running the centre."
The centre has been given quotes for a system with two security cameras, which would cost close to $5000.
The parents also plan to install outdoor lighting, and prune surrounding trees, giving would-be vandals fewer places to hide.
Ms Crow said the gates to the playground, previously open to the community, are padlocked after hours, with a "Trespassers Will Be Prosecuted Sign" put in place.
"It's a shame because we want to be open to our families. But we have to get the message across to these people."
Though the parents have been shaken, they are determined not to be beaten -- and are focusing on applying for grants for the upgrade, which will include a revamped kitchen and bathroom, improved cloakroom, insulation and a woodwork area.
"We're pretty staunch -- we'll get through it," playcentre mum Leah Wynne said.
