'Birrong' means 'stars' in Dharug, where students sleep under the starts (in tents) on journey-based expeditions. Our experienced Outdoor Education team has designed the off-site expedition program which includes two multi-day trips in the Greater Sydney and Central Coast areas including Bouddi National Park and The Great North Walk. Students will be in small groups with staff-to-student ratios of 2:17 maximum while on expedition.
