While the cyclone was not expected to hit the coast, severe weather and hazardous conditions are still forecast along the coast.
Forecasters said it's less likely that Cyclone Oma will cross the Queensland coast, but people are still being warned to expect high winds and risky swell.
A surfer taking on a large wave at Point Perry as swell from Cyclone Oma begins to arrive on the Sunshine Coast.
Oma was a weak category two storm early on Thursday, sitting about 950km northeast off Brisbane and is moving slowly towards the coast at around 10km/h.
But that doesn't mean the state will be spared its effects, with warnings issued for high winds and risky swell coinciding with king tides along the east coast from Thursday.
Increasing swell and abnormally high tides are expected south of Sandy Cap from Wednesday morning.
The Bureau of Meteorology warned: "Although Oma is not expected to make landfall in the coming days, it will be close enough to produce direct impacts along the Queensland and NSW coast".
Forecasters say the weather system will continue to bring high winds and unsafe surf conditions to parts of the Queensland and northern New South Wales coast in the coming days.
"Gale force winds, with gusts greater than 90km/hr, are expected to develop along exposed coastal areas of southern Queensland during Friday well ahead of Oma", the BOM said in a statement.
People in the cyclone watch zone have been urged to think about what preparations they might need to make if the cyclone threat increases.
The areas now most at risk of risky surf conditions are Fraser Island and Wide Bay coast north of Bargara.
Wide Bay Volunteer Marine Rescue's Bill Ker said conditions are likely to be particularly unsafe for small and recreational watercraft.
The worst effects are expected to be galeforce winds, very high swells that could erode beaches, and the possibility of heavy rain.
The Bureau has also issued a Flood Watch from Gladstone to the New South Wales border.
Sunny Nelson is set to pay the price for being known for its good weather as it avoids most of Cyclone Oma's wrath.
He said for Nelson to get rain, it needed a strong northerly.
While it is unusual for a cyclone to track this far south, it is not unprecedented.
BoM forecaster Adam Blazak said one of the scenarios was Oma may "linger" off the southeast coast and this potentially could have an enormous impact, creating a sustained deluge.
