School spokeswoman Tracey Pederson said the second annual event, combining a classic car and motorbike display with the school fair, raised more than $19,000 despite inclement weather.
The fair closed slightly early after rain rolled in, but she was ''thrilled with the turnout''.
''It was really well supported by the whole community.''
The money raised will go towards developments at the school, including playground improvements and performing arts resources.
