The girls have released a statement to their fans, letting them know that they've had to cancel specific dates due to "unavoidable scheduling conflicts."
Shows for Sydney, Melbourne and Brisbane have been moved to March.
Naturally, fans are annoyed about the rescheduled shows... but they're more upset that the girls have said nothing about it themselves.
Even so, Fifth Harmony's Twitter account tweeted about their 'last show' last weekend, seeming to forget about Australia completely.
The girls had already cancelled their New Zealand tour dates earlier this month.
