The launch of NBN's second satellite, Sky Muster II, has been delayed for 48 hours due to high winds at the launch site in French Guiana.
An NBN spokesperson said the high-altitude wind direction was to blame for the delay, and that the launch had be rescheduled as per its contingency plans.
Sky Muster II was set to take off from the French Guiana Space Centre and orbit 36,000km into the sky.
The new satellite, which was announced in July, will provide additional data capacity for providing satellite broadband services to regional areas of Australia who aren't eligible for a physical NBN connection.
NBN estimates that end users receive download speeds up to 25 Mbps and download speeds upload speeds up to 5 Mbps from the first satellite launched in October.
Skymuster also allows NBN resellers to supply wholesale broadband services from the satellite. Resellers include Activ8me, Ant Communications, Clear Networks, Harbour ISP, IPSTAR, reachnet and Sky Mesh.
Around 37,000 users were using interim services from the first Sky Muster, and it expects to hit 85,000 full-time users by June 2017.
NBN's goal is to connect 8 million homes and businesses by 2020.
