Shipping zone restriction for manual shipping

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.2.4
-- PHP version -- : 5.4.32

I am trying to get shipping zone restrictions working with manual shipping method.

At user registration i am using the following fields for address info.
address_street
address_street2 (for Suburb)
address_country
address_state
address_post_code
address_city

I have setup a country (Australia) zone, with a single state as a state subzone, then subzone of the state set as a shipping zone. If I apply the shipping zone as a restriction to the shipping method the shipping method doesn't appear at checkout even though the user has the shipping zone as part of their address (the problem occurs regardless of which address info field I try to match to the shipping zone. The same problem also occurs if I try to use the country or state zones as the restriction. What am I doing wrong?

Hello,
Are you sure that the shipping address that you have set through your checkout workflow is included on the zone that you have added through the "Zone" option of your shipping method configuration page ?
Can you please check it and show me some screenshots of how you configured your shipping method and your checkout workflow shipping address ?
Thanks.

Hi Screenshots of my checkout workflow and shipping method restrictions config are attached.

In the shipping method config, the Gold Coast zone is a shipping sub-zone of a state zone which is then a sub-zone of a country zone.

Hello,
Can you show me how did you configured through some screenshots :
- Your "Gold Coast" shipping zone via "Hikashop->System->Zones->'YourZone'"
- The shipping address that you are using through your checkout workflow.
