The actress and talent show judge told The Mail On Sunday that all the girls on the programme had to wear skimpy swimsuits, whatever the weather.
Minogue said: "For a lot of the time we girls had to wear a bikini - even in winter which, though nowhere near as cold as British winters, can still be chilly.
"I remember a few of us asking the producer if we could wear something less revealing, more suitable for the winter. The reply came back from the network: 'It's always summer in Summer Bay.'"
She added: "Apparently the British expect to enjoy summer when they turn on the television to watch the programme, so all the girls had to wear bikinis, even if meant us coming out in goosebumps."
Minogue joined Home and Away as rebellious teenager Emma Jackson in 1988, but only stayed on the show for one year.
