Welcome to OpenStreetMap! Phone numbers in Australia should be added to OSM according to the following format with the country and region code +61 x xxxx xxxx, (+61 xxx xxx xxx for mobiles) . You can get some other great tips from the Aussie wiki https://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines/Australian_features .  I have just updated the phone number to the correct format.

Thanks for mapping!

Cheers - Phil
