My family has a holiday home in Peterborough which is between Port Campbell and Warnambool, the Caravan park there is lovely right on the river, the beaches are very nice and clean(although notably unpatrolled) there are also rockpools, a little golf course, a play park and some tennis courts. Its about an 11 k drive to Port Campbell where there are some nice coffee shops. A bit more of a drive than Wye River from Lorne though!
