"I have three plans I am working on in parallel - two would see a concert take place on March 17 and one would see us cancelling the Mission concert for this year, which for all involved is the last thing we want to happen.

"People have made plans and made bookings, so my first aim is to find a line-up that people would want to see so that they can continue on."

Under the terms and conditions of buying Mission Estate concert tickets, SEL Management did not have to refund tickets if the line-up changed and the concert went ahead.

"Although we will endeavour to adhere to the publicised package contents, you accept that we and/or the event organisers have the right to alter elements of the event, including any advertised personal appearances, in our sole discretion."

However, should the concert be called off entirely, tickets would be fully refunded.

"We reserve the right to cancel or postpone an event for any reason. If we cancel an event we will provide a full refund to you."

Yesterday, it was announced tickets purchased by credit or debit card would be refunded in full (including ticket insurance premiums, if relevant). People should allow up to 10 working days for the refund to appear in your account.

Ticketek would also be in contact with patrons who purchased tickets with cash or eftpos, to arrange a refund.
