Scalpers have been put on notice, with about 1000 tickets to Taylor Swift's Melbourne concerts taken off re-sale sites over price gouging.
Acting Victorian Premier Ben Carroll confirmed authorities were keeping a close eye on those trying to sell tickets for more than 10 per cent above the market value.
"When you see the popularity of Taylor Swift and you see essentially everyone cramming to get tickets, it is no surprise that these tickets are in demand," he told reporters on Tuesday.
"But no family or no parent should be asked to spend literally thousands of dollars on a ticket that is normally priced as a few hundred."
In Victoria, it is illegal to sell or advertise for re-sale tickets to major events for more than 10 per cent above face value.
The state government in June declared Taylor Swift's three shows at the Melbourne Cricket Ground as major events.
Any ticket scalpers caught price gouging will receive a formal warning before facing fines of up to $10,000.
Corporations that facilitate the illegal sale of over-priced tickets can also be fined up to $50,000.
"As I speak, we are monitoring websites and we are tracking down and removing illegal tickets," Mr Carroll said.
"Anyone that does not obey those warnings and tries to come back for a second or third time on any of these sites selling tickets will feel the full force of the law."
Taylor Swift will be performing at the MCG for three concerts in February before making her way to Sydney for another four shows.
