So it turns out that Master Gremlin is waaaaay more talented at athletics than his old man. I'm looking at getting him and I to a track meet interstate early next year. I'm hoping to do it as a day trip and HLO. Previous meets he's been away for several days and checked in his track spikes in his luggage. Any idea whether these would be classified as a prohibited item? The Home Affairs website doesn't specifically call them out as prohibited, but would love it if someone can clarify one way or the other.
