Kawekas - Whittle Road

I am still new to the landscape, would it be safe travelling up Whittle road with entry level Triton?

Yip, no problem...just keep well left..

Unless things have changed a lot it will handle it fine, unless there is snow - I bounced my Terrano off a bank (gassed it to avoid sliding sideways on a sloping corner and suffered a lack of steering due to snow).
