As has been discussed both on this board as well as the BA board, QF have largely shut down their UK call centre and that TA component is pretty much all that is left of it.

The best way to contact QF is via their 24 hour number in Australia which can be found on their website, although to help you, their number is:

+61 (3) 9658 5302

Most of us UK based QF members always use the Australian number as the level of service is infinitely higher than what any of us experienced using the UK call centre. In addition to this, calls to Australia from the UK are generally priced the same as a UK local call so there is no difference in cost for most people. In fact my personal telephone package allows me to call Australia for free (except mobiles).

IMHO, don't bother with the UK office for anything. The above number should be able to assist with pretty much anything QF related.
