​Australians remain surprisingly keen on landline phones, but if you're paying for one then you're probably spending money unnecessarily.

More than half of us (55 per cent) still have a landline, according to a recent finder.com.au survey of 2005 Australians.

Given the choice, though, we'll nearly always opt to call with our mobile phone instead. Just 29 per cent of us say that we use our landline phone regularly, and 13 per cent of us have a landline but never use it.

Unsurprisingly, the most rusted-on landline users are older, with 52 per cent of Baby Boomers still using their landline for calls, compared with 10 per cent of Generation Y. That said, 16 per cent of Boomers have ditched their landline entirely.
