Do Australia passport holders need a visa to visit SS?

Yes, Australians need a visa for South Sudan. The simplest route is the official eVisa applied for online before you travel. Australian ordinary passport holders require a visa to enter South Sudan; there is no visa-free or visa-on-arrival entitlement for tourism. Because South Sudan has no diplomatic mission in Australia, the practical and recommended option is the official eVisa, applied for online at evisa.gov.ss (operated by the Ministry of Interior / Directorate of Nationality, Passports and Immigration). The standard product is a single-entry tourist eVisa, typically valid 90 days for entry with a stay of up to 30 days, at a fee of around USD 100. Applicants must hold a passport valid at least six months with a blank visa page, a valid Yellow Fever vaccination certificate (mandatory), a return ticket and proof of accommodation or a local address. Important: travellers whose passport contains a current or expired Israeli visa or stamp can be refused entry. Apply at least 1-2 weeks before departure and carry a printed copy of the approved eVisa, as it must be presented on arrival.
