All non-Australian citizens travelling to Australia require a visa.
If you have a valid New Zealand passport, you can travel to Australia and you will be issued with a Special Category Visa (SCV) on arrival.
See the Department of Immigration and Border Protection website for details on visitor visa options. In particular, citizens from some eligible countries can apply online for an eVisitor visa or an Electronic Travel Authority (ETA).
From overseas you will arrive at Sydney (Kingsford Smith) Airport Terminal 1. From other cities in Australia you will arrive at Sydney Airport Terminal 2 or Terminal 3. Sydney airport is about 14km away from the University of Technology, Sydney (UTS).
From all terminals of the airport to UTS: a taxi ride would take 40 minutes and should cost around $50. All taxis are licenced and all journeys are metered.
From all terminals of the airport to the city: the Airport Link train runs regularly and takes about 15 minutes to reach Central Station. From there you can walk to UTS or you can take the City Circle train to all central destinations.
Sydney has an extensive public transport network involving trains, buses and ferries, see Transport NSW for full details. You will need an Opal card or an Opal single trip ticket.
Opal cards can be obtained and topped up at outlets such as newsagencies and convenience stores. Opal card fares are automatically calculated and deducted from your card based on where you tap on to where you tap off. You can purchase an Opal single bus ticket from the driver on board, with the exception that some bus routes are PrePay (cashless) at all times while some bus stops are PrePay at certain times of the day.
If travelling with a group of people, a taxi could be an affordable alternative. These can be hailed on the street or ordered by telephone. Uber and GoCatch are also very popular in Sydney.
The conference will be held at UTS Business School (Building 8). It is a walking distance (approximately 7 minutes) from Central Station, which is the main train station in Sydney and one of stops when taking the train from the airport. The closest bus stop is Railway Square and many of the main bus lines in Sydney stop here. Parking is restricted to specific areas and is typically expensive.
