If you want to take children’s wooden indoor toys to Australia. They may be asked where they obtained them from, and if they’re not travelling from a high risk country and you bought them from a reputable source, i.e. a toy store, they might be waved through without visual inspection.
A visual or X-ray inspection may be required, in which case they need to be pulled out and handed over. This is done to look for borer holes or larvae inside the toy. If nothing’s found, they’re get them back.
If something of concern is found, generally they will be taken away for fumigation and quarantine and can be picked up at a later date. IIRC this is done at the cost of the person bringing in the wooden objects.
It’s possible that they might be destroyed completely but I haven’t heard of that happening despite bringing objects falling into all three steps at different times.
