Key officials accompanied the parliamentarians who toured industry, services and infrastructure in Port Augusta between Wednesday and Friday.

Kick starting the party's planning for its approach to the 2010 election, opposition leader Martin Hamilton-Smith outlined water security, health and his push for the 2018 Commonwealth Games as key selling points to the party's campaign.

A strong rural focus is set for the party's agenda, Mr Hamilton-Smith said.

"Look around my party room and you see country faces," he said.

"Mr Rann's government is city focused and only have Lyn Breuer in a regional area, it's only natural they wouldn't care about the country."

In fact the seat of Giles and Light are both held by the State Government, which boasts two former country dwellers, Karlene Maywald and Rory McEwen as well, a spokesperson for the premier said.

"Since the Rann Government came to office in 2002, there have been 42 community cabinet meetings," the spokesperson said.

"It's pleasing to see that Mr Hamilton-Smith is now trying to copy this program."

But while the opposition was formulating an election campaign in its time in the city, it was also discussing Mr Hamilton-Smith's push for the 2018 Commonwealth Games.

Mr Hamilton-Smith hoped that the games would not only benefit people in Adelaide but would spill over to regional areas.

"It will act as a lightning rod for development of sport infrastructure across the State," Mr Hamilton-Smith said.

"Fifty-thousand people will come to the games.

"There's a lot to see in South Australia outside Adelaide."

Water security and the development of a desalination plant to service the Upper Spencer Gulf was also something the party would be looking into for its election campaign.

The leader laid down claims that a proposed plant for the gulf was being neglected by the Rann and Rudd governments and said that the party looked towards securing a clean water supply for regional areas, despite the government being in talks with BHP Billiton about involvement in a plant in the gulf.

The opposition cabinet was in the city for three days and toured health services, the power stations, schools and the railyards before leaving on Friday.
