Wild surf conditions are expected off the South East Queensland and New South Wales coasts as early as Thursday as Tropical Cyclone Uesi tracks closer to Australia.

Key points: Tropical Cyclone Uesi will not reach the Australian coast but will bring some big swells

The category-three system is currently west of Noumea, but expected to weaken as it nears Australia.

The Bureau of Meteorology's (BOM) Helen Kirkup said it would still produce swells of up to 5.5 metres as it tracks along the New South Wales coast.

"What we also have on top of that is some fairly high tides at the moment," she said.

"It's expected that the combination of king tides and big swells may contribute to more coastal erosion."

However, Ms Kirkup said rain from the cyclone was unlikely to reach the coast.

"Unless it does tend to track a bit more to the west. The rainfall is more likely to stay off shore," she said.

Forecaster Kimba Wong said Queensland will also see big surf with a 2m to 2.5m easterly swell expected on Thursday.

"At this stage we're not expecting direct cyclone impacts on the Queensland east coast, as it's expected to remain offshore for the time being," Ms Wong said.

"What we are expecting, though, as we head into the end of this week, particularly from Thursday onwards, is anywhere south of Fraser Island will see some increased easterly swell."

The swell could peak as high as 3.5m on Friday when hazardous surf conditions and high winds are likely.

BOM has encouraged surfers and mariners to keep up to date with conditions towards the end of the week.

It has now issued its first Tropical Cyclone Advice for the weakening system, warning it is moving towards Lord Howe Island.

Ms Kirkup said the island is likely to cop the brunt of the cyclone.

"It's going to be fairly close to the current estimated track of this cyclone," she said.

"They're estimating [on Thursday] they will see gales with gusts of up to 120 kilometres per hour, on top of that we going to see hazardous surf conditions."
