Tourism operators say a new air link between Christchurch and Perth will be a big boost for the industry.
Air New Zealand and Virgin Australia have announced twice weekly services over summer, the first direct service between the two cities in more than 20 years.
Tourism Holdings chief executive Grant Webster said it was great news for the South Island and New Zealand tourism.
"As an operator in both Perth and Christchurch, we can see the opportunity in Western Australia both inbound and outbound. Perth is basically our largest Australian branch now and shows on-going growth."
Chief executive of Ngai Tahu Tourism John Thorburn said Western Australian visitors would stay longer and do more activities, making this market an attractive opportunity for his company and the wider industry."
