No - I don't think it's C. decumbens, as its anthers are more exserted from the flower (e.g. see https://www.anbg.gov.au/photo/apii/id/dig/50589). At that location it would definitely be either planted or self sown from a cultivated plant.
A more upright form of Correa decumbens? Spreading nature, oblong to narrow elliptical leaves and narrow cylindrical, pink to red flowers with green lobes. An escapee or planted?
