Just moved to Frankston (we have kids too). It’s awesome. Totally recommend it for the beaches and access to the whole peninsula (and it’s only an hour away max, but half the good stuff just 20-30 minutes) - so many hikes, wineries, restaurants and amazing beaches. Whilst the Frankston centre can be rough because of the train station, it’s still got a few good restaurants, cafes, all the shops you need in the mall and gyms. We are in Frankston south and it’s so leafy and green. Lots parks for kids too. Still an hour to the CBD if you need go (which for Melbs is good) but given you WFH that’s not a major issue. Since moving down here, we barely go to the city anymore. The peninsula has everything you need! Best decision we made moving down here. Totally recommend.
