Police responded to an anonymous tip-off from a passer-by, who said he had spotted people loading items into a white ute about 3am on January 17.
Police attended to find the hall had been ransacked.
Racist graffiti had been painted across the walls, tomato sauce thrown around and cupboards and windows smashed.
The cost of the damage and property loss is estimated at $10,000.
Police reported that the majority of the stolen items, mostly audio equipment, had been recovered.
Cleaning and repairs were quickly made to the hall to have it ready for the annual Australia Day ceremony.
Residents expressed disgust at the incident and commented on social media.
One Lower Chittering resident said it was ‘extremely disappointing’ to see the hall vandalised after so much community effort had gone into it.
‘What frustrated me was how they had smashed the cupboards to smithereens,’ the resident said.
‘The destruction was pointless as they did not achieve anything financially.
‘Their absurd and unnecessary destruction left the hall in a disgusting state.’
The two 18-year-olds are due to appear in Moora Magistrates Court today, and the 16-year-old will appear in Moora Children’s Court on the same day.
