Private Speech Therapist Recommendation for bilingual 3 year old - Melbourne/Western Suburbs

Hi there!
Can anyone recommend a Private Speech Therapist for my three year old son, preferrably someone specialised in bilingual children or at least someone open to the idea of biligualism. We live in Hobsons Bay (Melbourne/ Western Suburbs), somebody in the area would be nice but we are also happy to travel for the right therapist. We got a referral from our MCHN to a public Speech Pathology. Unfortunately, the waiting period would be at least 12 months and we would incurr quite high fees anyway because they base their fees on your income. Does anyone know how long waiting periods are in the private sector? At this stage, I would like to get an assessment done asap to see if we need to take further steps. My son is also booked in for a hearing test, I don't think there is anything wrong with his hearing, though. Thanks heaps.
