Residents and tourists of Queensland's Gold and Sunshine coasts found themselves navigating through miles of thick sea foam over the weekend.

Tropical cyclone Oswald pummeled the coast last week, churning up the ocean, which in turn spewed forth the fluffy foam. The strange brew spread across the coastline and into town ? causing issues for drivers, pedestrians and local businesses.

Witnesses report the foam measured up to 10-feet thick in some areas.
