I love all the qualifications that accompany why this is a "standard" visual approach:
once you have washed off any access height initially
If you are properly configured, on speed, and commence
descent immediately you pass overhead SHEED, unless you have a screaming easterly, you will have no trouble getting on slope and stabilised within the criteria.
Just because you're doing 1500ft/min at 1500ft doesn't mean the approach is unstable.
There is no other visual approach off a STAR in Australia that requires any special considerations in terms of descent profile or configuration. All the others put you at 10 miles 3000' which is a
standard descent point and profile with the aircraft being configured as the descent is maintained. The only reason this approach exists is because "we've always done it this way". If that is a valid reason for not changing anything then why not continue with the practice of 300kts to 20 miles, after all that would be the most economical and quickest way of processing traffic in the TMA. Its the way it used to be done and it was a lot of fun as well.
