Cross the Ditch 23

Cross the Ditch 23

Summer 2022

December brings summer weather to the South Pacific, complete with scorching sun, soaring temperatures, and more than a few thunderstorms.

For VATSIM's pilots and controllers the answer is obvious: it's time to once again take to the virtual skies and Cross the Ditch!

What's it all about?

For twenty hours this December, the skies over the Tasman Sea between Australia and New Zealand will be filled with aircraft all on a mission to Cross the Ditch.

An example of that typical down-under understatement, this "ditch" is over 1100nm wide. The flight routes all range from two and a half to three and a half hours flight time.

Throughout the event, Oceania's two divisions – VATNZ and VATPAC – will be providing full gate-to-gate ATC coverage, in the Southern Hemisphere's premiere oceanic event.

This is a great opportunity to experience Oceanic flying without the need to commit to an eight-hour flight!

If you're new to Oceanic Flying, our reporting tool makes taking part a breeze.

Event Times

This twenty hour event is timed to allow pilots from all over the world to join the fun:


This season's event is organised in waves. Each airport will have a three-to-four-and-a-half hour departure window, during which time flights will be able to leave for the next destination. As the window closes, the departure window will open at the next destination.

Given each of the flights is 3 - 4.5hrs in length, the previous wave's flights will be arriving at the same airport as the next wave departs, maximising the amount of traffic at each airport.

NOTE: in order to ensure that you have ATC coverage throughout your flight, you MUST fly the wave route that is active at the time of your departure.

The individual routes are designed to ensure as much opposing traffic enroute as possible.

Each flight passes from one Oceania division to the other, and the result is six mini-flyins over the course of twenty hours!
