Summer holidays, with room to slow down.

Summer runs from December to February. For a family beach holiday, start by choosing the stretch of coast you actually want to spend time on, rather than the longest list of attractions. For friends travelling together, decide whether the centre of the trip is the beach, food and wine, or a slower few days at a shared home. That decision makes the rest of the planning much easier.

Victoria and the Gold Coast need different plans. Victoria can move between hot afternoons and cooler coastal weather; the Gold Coast's subtropical summer brings humidity and the possibility of afternoon storms. Choose one outdoor priority each day and give it a backup. This is a planning guide, not a forecast: check the conditions for your actual dates before booking weather-dependent activities.

For a first Peninsula summer, pick a bay-side base if beach days are the priority. Spend a morning around Mount Martha, Dromana or Sorrento, then leave the middle of the day for lunch or a rest. The ocean side is a different outing, with surf and exposed coastline rather than an interchangeable family-swimming option. Plan the day's beach around current patrols and conditions.

A second day can be for the hills: a booked lunch around Red Hill or Merricks, with one cellar door rather than a rushed tasting circuit. Arrange your transport before wine tasting. For a group, a picnic-style lunch back at the home can be simpler than another restaurant booking. Our Peninsula area guide has the individual beaches, walks and local places.

Choose the valley if summer means a shared table, countryside and a few well-planned outings. Start with Yarra Glen or Healesville as a base for the part of the region you want to explore. Put your main winery lunch in the diary first, then build one nearby stop around it. A long tasting day and an early sunrise activity make a tiring combination, so separate them if possible.

For families, alternate a grown-up lunch with an outing chosen for the children. Confirm the venue's current family arrangements before booking. A balloon flight is an optional highlight, subject to the operator's weather decision; keep another morning activity available. You do not need a winery appointment on every day of a valley stay.

Summer is the busy season on the Great Ocean Road, particularly around the late-December and January holiday period. Choose a home base and explore outward rather than treating every day as another relocation. A stay around Wye River or the nearby coast can be about the beach, a village lunch and a short local outing, with a separate day for a longer drive.

The Twelve Apostles are a distinct excursion, not a quick stop around the corner from every coastal town. Check your route before promising the group a morning at the beach and an afternoon far along the coast. Use designated lookout parking, leave extra time for stops and keep the final drive manageable. The region's official trip-planning information is linked below.

For a beach-focused summer, choose the neighbourhood first: being near the stretch of coast your group likes is more useful than planning to cross the city repeatedly. Keep mornings for a beach visit or an outdoor activity, then leave a flexible afternoon for lunch, shopping or time together. Warm weather does not make every beach or creek suitable for swimming on every day.

For theme-park families, reserve a whole day rather than adding a park between other plans. For friends, one organised dinner can anchor the trip while the other evenings stay easy. Summer storms can alter outdoor plans. A covered dining area or comfortable shared living room may matter as much as the pool when comparing homes.

• December

  Decide early whether this is a pre-Christmas escape or a Christmas and New Year trip. They require different levels of coordination. Confirm restaurant and attraction opening arrangements directly, organise the group's arrivals and avoid assuming that a normal weekly timetable applies on public holidays.

• January

  Give the holiday a simple daily rhythm: one outing, a meal plan and time without bookings. Check the relevant school-holiday calendar and leave room for traffic and busy car parks. For a larger group, nominate who is bringing the first night's groceries before everyone sets off.

• February

  If your dates are flexible, compare February with the holiday dates that suit your group. Do not assume it is quieter or cheaper for a particular home; use actual availability and complete prices. Keep the summer plan flexible enough to swap a beach day with a food, gallery or indoor outing.

Use this as a starting point, then adapt the locations and pace to your group. These are suggested plans, not bookable packages or promises of opening times.

• Arrival afternoon

  Arrive without a major excursion attached. Settle the sleeping arrangements, check the guest information and choose somewhere close for dinner or cook together. A short walk nearby is enough for the first evening. Keep any pool or beach plan dependent on supervision, house rules and conditions.

• Your full day

  Pick either a beach morning or the region's main outing, then allow a real lunch break. On the Peninsula that might mean beach followed by a lunch in the hills; in the valley, a booked winery lunch; on the coast, a local drive; on the Gold Coast, a dedicated activity day.

• Departure day

  Pack before the final outing and follow the home's check-out time. Choose breakfast or a short walk that does not send you away from the route home. If the group wants another full day, check parking, luggage and venue arrangements rather than assuming the home can hold bags after check-out.

With children, keep at least one meal and one activity simple each day. Check cot availability, stair layouts, pool fencing information and sleeping arrangements for the specific home. Those details vary. For swimming, choose a patrolled beach and follow the red and yellow flags and local advice; a beach photo does not establish safe conditions.

Pack for the place, not just the season: hats, appropriate sun protection, walking shoes, a light layer and something for a change in weather. For outdoor trips, check the current Bureau forecast, local alerts and the operator's advice. Book key experiences with enough time to read their cancellation and weather policies.

For weddings or a large family gathering, start with the actual sleeping layout and transport plan. A holiday home is accommodation; permission to hold an event must never be inferred from a large lawn or dining table. Compare the complete stay price for your dates and party, then read payment, cancellation and security-hold details before paying.
