1300 numbers are specific to Australia and can only be dialed from phones within the telecommunications network in Australia.
If you do need to provide a phone number for callers outside of Australia, we suggest providing a specific +61 number for this task. We can supply you a dedicated number for this that has a full set of routing options just like the 1300 number does. The services is called “Line Hunt” and is available for $10 per month. For more details on Line Hunt you can contact us here.
You can connect your 1300 number to almost any international destination. Different pricing applies depending on the destination country, see here for specific 1300 international pricing.
