PINJARRA St Vinnies is urging people to donate goods with an influx of Yarloop evacuees expected to hit town Friday afternoon.
The George Street store has been accepting donations since yesterday but is in need of more.
Shop volunteer manager Barbara Anderson said there had been confusion as to where people were suppose to be dropping things.
"The evacuation centre is becoming quite busy and they don't have room for the donations," she said.
"We have a lot of stuff already but need more, camping equipment, bed linen, food and clothing."
Evacuees can visit the store between 9am and 4pm Monday to Friday and 9am to 12noon on Saturday.
"They can help themselves to whatever is available, whatever they need they can have," Ms Anderson said.
On Thursday Ms Anderson said a man who was saturated after being rescued from Preston beach visited the store seeking clothes.
"We have a container bin filled with goods being delivered from Mandurah this afternoon," she said.
Unfortunately, Ms Anderson said it wasn't the first time the community had to rally like this but the situation in comparison to past fires was "probably worse".
"We are lucky the community is so wonderful," she said.
"Coles have donated bread, Subway sent over sandwiches to the centre and pizzas have also been delivered.
"We just encourage people to keep giving where they can."
