Australian tourists planning to visit Egypt are warned to "exercise a high degree of caution" about the country's current anti-government rallies in Cairo and other regions, as posted in the Australian government's Smartraveller website.

Foreign Minister Bob Carr said that the country would not be raising its travel alert to the Middle East but the political unrest could change in the following days to come. Senator Carr is currently in Brunei for a meeting.

"Australia urges its citizens to exercise a high degree of caution in Egypt due to the risk of civil unrest. Canada, UK, and NZ have issued similar warnings," he said.

He added that, "We're not aware of any risk that Australians would be targeted, but anyone could be caught up in violent exchanges."

Millions of people are rallying in the streets of Cairo and other areas in Egypt to protest against the Morsi Government.

At least three people have been killed in the recent unrest while 40 others were injured when supporters and opponents of Morsi clashed in Beni Sueif.

Meanwhile, Australian tour companies are diverting tourists away from Cairo by changing itineraries, hotels and routings to keep them away from the demonstration areas.

"We contacted all guests ahead of departing for Egypt and while rescheduling and a full refund were offered, those booked with Trafalgar were undeterred," said Matt Cameron-Smith, managing director of Trafalgar.

While Abercrombie & Kent's managing director Suajta Raman said that, "Sales have been volatile as Egypt has had a few civil disturbances, but they have tended to come back quickly."

Raman made it clear that the demonstrations are only in Cairo but not in Upper Egypt where it continues to remain relatively calm.

In addition, Travel Insurance Direct's Phil Sylvester said the unrests are usually limited in particular locations.

"It's a big location, but the Antiquities museum happens to be on one side, which makes it essential to plan your visit to avoid protests.

"The place where most tourists go is Giza and the Pyramids, which has so far remained trouble-free," he said.
