Bringing a full box of used shuttlecocks into Australia

I’m flying back to Australia soon and I want to bring a full box of feather shuttlecocks (around 30 tubes) from Malaysia. They’re mostly training shuttles and not really old or dirty. I know feather shuttlecocks count as animal products, so I plan to declare them on arrival.

My question is:
Is bringing this quantity actually fine, or could it be considered risky or illegal?
Has anyone brought a large amount before, and what did customs do?
