What it means
Means to have a rummage about, nosey but in a relaxed, curious way, like you’re half searching and half enjoying the clutter. You can fossick through drawers, an op shop, a garage sale, or the back of the shed looking for a hidden gem. The word comes from goldfield days, when prospectors fossicked for bits of gold.
Usage examples
"Stop fossicking in the shed, Mum yelled. I’m trying to find my old cricket bat, but I keep turning up stubby holders and dust."
"I had a good fossick through the shed and found Dad's old fishing gear under a pile of tarps."
"She loves fossicking in op shops, came home with a vintage teapot and three records for a fiver."
"We were fossicking round Nan's spare room and found a biscuit tin full of old footy cards."
"Had a fossick in the op shop on Saturday and walked out with a denim jacket and a lamp shaped like a swan."
Where it comes from
Fossick is old Australian English born in the gold rush days of the 1850s. Back then it meant scratching through earth, spoil, or abandoned diggings for leftover bits of gold. The word is generally traced to British dialect roots, and in Australia it drifted beautifully into the wider sense of rummaging around for anything worth finding.
