"It will be the largest navy ship to arrive in Napier."
The 177-metre long ship is stopping by to give its crew of around 170 officers, senior NCOs and other ratings, as well as troops, a spot of rest and relaxation before the intensive exercise.
"They will have the chance to have a quick look around Napier."
HMAS Choules is scheduled to tie up at 7am on Wednesday and depart at 10am on Friday.
It will not be open to the public.
Mr Smith said there had always been a long and strong connection between Hawke's Bay and the navies of both countries, and felt it was a privilege to get such an integral part of the Australian navy's logistical support fleet to call in.
He believed it was the friendly links forged in the past which saw the Australian Defence Force decide to steer it toward Napier before taking part in Exercise Southern Katipo.
Mr Smith also pondered if the Australian Defence Attache, who was a guest here for the Tremains Art Deco Festival, may have also put in a good word for the city.
Exercise Southern Katipo is based around a scenario of a troubled region called Becara which is suffering political instability and unrest.
The South Island spots will make up the land of Becara with New Zealand called in to assemble and lead an intervention force comprising a coalition of Pacific Island Forum member states.
For the crew of HMAS Choules the exercise comes on the tail of a real emergency callout, with the ship called in to assist with humanitarian needs in Vanuatu late last month when residents had to evacuate under the risk of a volcanic eruption.
