This looks like the correct regular expression for what you need and my
suggestion is probably just a personal preference but if you have pattern
groups that are OR:ed together I find it much easier to read if they are in
separate pattern elements. So, in the case above I would write the type as:

<xs:simpleType name="phoneType">
   <xs:restriction base="xs:string">
      <xs:pattern value="(04)?[0-9]{8}"/>
      <xs:pattern value="(\+614)?[0-9]{8}"/>
   </xs:restriction>
</xs:simpleType>

Since, multiple pattern elements are OR:ed together the result will be the
same.
