I agree with TnT - that is how I read it too.
Your husband would be covered by your credit card policy but you would need to take out cover with another company to cover yourself as a pillon passenger.
For example see 1 Covers policy on page 80-81 (http://www.1cover.com.au/assets/pdf/1Cover-Standard-PDS.pdf) it talks about being a passenger on a bike that is in control of a person with a licence valid in the county of travel.
As your husband has an Australian and International licence I believe that as a passenger you would be covered by 1 Cover.
Would be interested to hear any differing views but this is how I interpret the PDS.
