Do Australia passport holders need a visa to visit NP?

Australian ordinary passport holders do NOT need a visa in advance for tourism in Nepal. A multiple-entry tourist visa is issued on arrival at Tribhuvan International Airport (Kathmandu) and at land border crossings. Fees are USD 30 (15 days), USD 50 (30 days) or USD 125 (90 days), payable in cash. You can also pre-fill the online form within 15 days of travel to speed up the airport queue. Nepal grants visa on arrival to nationals of most countries, including Australia. An Australian ordinary passport holder traveling for tourism receives a multiple-entry tourist visa on arrival at Tribhuvan International Airport in Kathmandu and at designated land border posts. The visa is sold in three durations: 15 days for USD 30, 30 days for USD 50, and 90 days for USD 125. Fees are paid at the airport (USD cash preferred; other major currencies including AUD accepted at desks, and EFTPOS/card available at the airport visa counters). The passport must be valid for at least six months. Travelers may instead apply at the Embassy of Nepal in Canberra, or complete the official online pre-arrival form at nepaliport.immigration.gov.np within 15 days of departure to reduce time at the immigration desk. Tourists may stay a maximum of 150 days within a single calendar year (January-December), and visas can be extended in-country (minimum 15-day extension for USD 45, plus USD 3 per additional day). This route is firmly visa-on-arrival; no prior visa is required for a short tourist stay.
