Australia batsman Michael Hussey says South Africa's bowlers will provide him with the hardest examination of his Test career.
Hussey averages 64.18 in 31 Tests since making his debut at the age of 30 against West Indies three years ago.
Australia and South Africa, ranked first and second in the world by the International Cricket Council, go up against each other in a three-Test series, starting in Perth on Wednesday.
And Hussey is under no illusions about the size of Australia's task as they look to defend a 16-year unbeaten home record.
"They're a fantastic team," Hussey told The Wisden Cricketer.
"From a batting point of view they've arguably got the best bowling attack that we'll come up against anywhere in the world.
"If we get them in Australian and South African conditions, as we will this summer, it's going to be extremely challenging.
"But that's what we want. We want to play against the best around the world.
"We want to show everyone that we are still, hopefully, the number one team in the world."
Hussey is also a regular in Australia's limited-overs line-up and is contracted to the Chennai Super Kings in the Indian Premier League.
He believes playing Twenty20 has helped make him a better cricketer.
"I think Twenty20 is good for the game. It's going to improve the skills of the players," he said.
"We cater for all sectors of the market. If we can get kids involved in Twenty20 cricket to start with, get them falling in love with the game, and then introduce them to the other forms, I think that can only be good.
"However, I also think that we can flood the market too much with Twenty20 and it may lose some of its attractiveness. We need to make sure that we don't play too much of any form of the game, to make it special for everyone."
