I bought an on site ticket for Newcastle Australia & need to change it to off site. Happy to buy 2nd

Due to sudden personal issues I now cant attend an on site anomoly.
How can I buy another ticket for off site so I get the medal please?
Cant seem to edit my current purchase via the scanner.
Thank you
