brock I ordered mine from Supercheap online http://www.supercheapauto.com.au/vehicle-search/parts-guide
ICEDVOVO Download the Mackay rubber catalogue ( they also make stuff like exhaust hangers and suspension bushes) Then get the correct part number for the hoses. Then check ebay for lowest price for that part number. There is a guy on ebay who sells nothing but Mackay rubber bits. And cross check price at supercheap but keep in mind their part selector is not bullet proof. And taking on-line stuff back to a Supercheap store is a PITA. Mackay used to make their parts from Aussie grown rubber as well. Not so sure about that now though. Maybe even they outsource some of their manufacturing now
