Bunnings products?

Anyone know of decent supplies you can get (physical store preffered) if you only have a Bunnings? I like the cheap small Northcote terracotta pots great for keikis. But... I find the Osmacote Orchid mix has too much dirt and the Brunnings perlite is too fine for orchids. Also any thoughts on a good handheld sprayer/pump mister? That cheap 3 pack of multiculoured sprayers needs adjusting and the hose misters are not precise enough to avoid crowns... Any bunnings available recommendations for mounting an orchid to wood? I feel like jute is too fiddly and wire is too harsh? (If it matters, I have about 60 mixxed dens, phals, oncidium, rhyncho and one each of brassalova, cattleya and vanda in outdoors in Townsville.
