On the first day of spring that temperatures have passed the mid-20s the CFS have been called to their first bushfire in the Hills.

Residents near Montacute in the Adelaide Hills have been advised to check and follow their Bushfire Survival Plans.

The CFS are attending a fire near Institute Road and Moores Road.

High winds and heavy fuel loads in the area will provide challenging conditions for the crews, with motorists asked to avoid the area and be aware of fire units moving through the zone near the Morialta Conservation Park.

The CFS reports that the fire is currently totally inaccessible, burning in heavy scrub and travelling from the Instute Road towards the Moores Road area.

A strip of approximately 300 metres of native vegetation has been burnt.

No structures were reported to be in the path or the immediate vicinity of the fire.

CFS crews also responded to a grassfire in Woodside - the fire is now listed by the CFS as complete.

Update - 3:10pm

The CFS advise the Montacute fire was a burn-off on private land that jumped containment lines.

30 firefighters from the CFS and Department of Environment, Water and Natural Resources are attempting to control the fire.

The fire has now burnt approximately 10 hectares of scrubland, but is still not posing a threat to nearby properties.

Residents in the area are advised to close doors and windows and remain indoors if smoke is causing them concern.

Road users are advised to use caution in the area as smoke may reduce visibility.
