It would seem that unless I re-read all of the fine print within my Covermore Travel Insurance policy wording and then sick some lawyers on to them, that Covermore aren't likely to be forthcoming in reimbursing me any more money and as a result I'm going to be out of pocket as far as repairing my bike is concerned, etc.
Now on a slightly more positive note however, it would seem that I may be a little more fortuitous as far as my Australian medical expenses are concerned, because it transpires that my membership of Bicycle Victoria also includes a certain amount of insurance coverage as well as access to legal aid.
I'll let you know how I get on in due course...
