Midnight arrival into Maroochydore?

[Roland R]

Hey guys I rarely get time to read or post in YSSY these days, but am hoping someone can help.

Just got of the phone from dear old Mum who's been retired to Maroochy for years now and both Mum and Dad are always interested when they see or hear something unusual in aviation.

Mum said she heard a "regular sounding" aircraft come in last night, but at midnight... She says most flights generally stop around 8:30 to 10:00pm at the latest... Usually!

She's wondering if there was a divert, delay or special flight?
