Once again the whale season has kicked off early, with tour boat operators reporting a greater volume of whales than ever before.

"It kicked off around the middle of May and we have had no misses so far," Frank Future from Imagine Cruises said.

This increase in whale sightings isn't slowing down, with wildlife management officer Geoff Ross from the NSW National Parks and Wildlife Service (NPWS) reporting the whale population is growing 14 per cent.

"There are an increasing number of humpback whales passing Port Stephens, along with right whales and minke whales," he said.

The whales are migrating north where the seas are warmer so they can give birth to their calves.

Mr Ross said now is a great time for whale spotting, especially from the headland.

"You can always take some binoculars and wear warm clothes and when sunny apply sunscreen," he said. "They are so majestic and to be 100 metres from such a large animal fills me with great awe."

The NPWS spend whale season doing compliance operations on-board commercial whale watching vessels and from the shoreline to ensure the migration goes smoothly and safely.
