The campaign is a process to select the seven best natural sites in world, with Table Mountain remaining as one of the 28 finalists out of an initial list of 440 sites in 220 countries.

Winde urged residents, with just over four months left of the four-year campaign, to vote for Table Mountain if it is going to make it on the final list.

"We are up against stiff competition, including Uluru (Ayers Rock) in Australia, and we are currently not in a winning spot. However, I am confident that if Western Cape residents display their trademark team spirit and get behind this campaign, we can still climb to the top of the list."

New 7 Wonders campaign manager, Fiona Furey, said on Tuesday that it was time for all South Africans to “get behind their mountain,” adding that Winde has shown support for the Vote for Table Mountain campaign since 2009.

People can vote by SMSing “Table” to 34874 or by voting online at www.votefortablemountain.com.
