Rassie Erasmus admits Boks don't know what to expect from Eddie Jones' Wallabies

Speaking to reporters on Thursday, Erasmus reminded everyone of the famous quote from the 1994 film Forrest Gump when he said that Australia's new coach Eddie Jones "is like a box of chocolates - you never know what you are going to get".

An unpredictable coach by nature, this will also be Jones' first official game in charge since he began his second stint as Wallabies coach, a combination that the Bok coaches admit has them unsure just what kind of approach their opponents will be adopting this weekend.

"It is difficult from a South African perspective to figure out what he (Jones) will do," Erasmus told reporters ahead of Saturday's sell-out clash at Loftus Versfeld.

"Australia have not played any warm-up games that would give us some insights.

"I do not know how much they will be able to change for us - but I do know that Eddie will try to get his team to outmuscle us."

While Erasmus reckons it's unlikely the Wallabies will be a totally changed side right out of the gate, he believes Australia and Jones are a match made in heaven.

"I always feel that a South African working with South Africans will get the best out of South Africans," he said.

"Similarly, I think an Australian working with Australians will get the best out of them. He knows the Aussie setup."

Nevertheless, Erasmus reckons it will probably take Jones "three to four matches" to put his stamp on Australia.

Meanwhile, Erasmus was again asked about the Boks' decision to split squads for their matches against the Wallabies and the All Blacks, and again insisted it had nothing to do with disrespecting Australia.

In fact, he said, it was just the opposite.

"I can tell you we don't disrespect them - that is why we are only letting the guys fly across [on Tuesday] and [on Wednesday] because we want proper preparation. We have been preparing for three weeks for Australia," said Erasmus, the national director of rugby.

"It's more respect for the competition and not a lack of respect for Australia. We wouldn't have a chance against New Zealand if we arrive there on a Tuesday [next week], have one training session, and play them after a side like Australia.

"I'm pretty sure it will be a very competitive match on Saturday and Eddie will get that."

Wallaby utility back Reece Hodge made it clear on Thursday that they do not see the Springbok team selected for this weekend's match as anything less than a formidable side.

"They have the luxury of four or five or six guys in every position. Make no mistake, it's a very high-quality team and it's going to be a massive test for us," he said.

"They're going to be coming out firing in their first home test of the year so we don't really expect too much different there in terms of selection."
