Australian Foreign Affairs has reissued its travel advisory for Madagascar, adding to earlier warnings about security and safety.

The new advice deals with civil unrest, politcal tension and crime, specifically carjackings and theft from vehicles.

The overall level of advice, which suggests that Australians reconsider the need to travel to Madagascar at this time, has not changed.

Foreign Affairs has also updated its Honduras travel advisory, adding information about civil unrest and political tension following the swearing-in of a new government.

But the overall warning level has decreased.

Retail group TravelManagers says rail travel is becoming "incredibly trendy" and believes it will be a strong seller for the network this year.

The comment comes as staff from seven locations in NSW, Victoria and Queensland head to Darwin for a two-night journey to Adelaide on the Ghan.

The seven have become accredited Great Southern Rail specialists after achieving a 90% examination pass rate.

Pru Gallagher from TravelManagers national partnership office says another four exclusive famils are in the pipeline and there’ll be 23 travel managers on educationals with suppliers in the first months of this year.
