The St Ives area was first explored by Governor
Arthur Phillip and a party of men in 1788 where they set up a campsite at
Bungaroo which is close to what is now Hunter Avenue. The area produced a small-scale timber felling industry. There are still some examples of the thirty-metre and higher trees in nearby Pymble in the
Dalrymple-Hay Nature Reserve and near Canisius College. Native
turpentine trees were also once abundant and provided useful timber for cabinet making. It was once known for its apple orchards, but due to residential demand, there is no longer any commercial fruit growing in the area. During the
Second World War, there were significant numbers of troops barracked in the area, which provided the impetus to build Archbold Road as a supplementary and emergency route to the city. Since 1950 the suburb has expanded from the central shopping areas and the arterial main roads to include hilltop and valley areas bordering on the surrounding
Ku-ring-gai Chase National Park to the north, now the area known as
St Ives Chase, and
Garigal National Park to the east and the south-east. St Ives Post Office opened on 10 November 1885 and the first public school opened on 6 May 1889. The school was formally opened by
John Burns,
MLA on Saturday 8 June. After inspecting the "neat and well-designed school and teacher's residence" the party had a luncheon to mark the occasion. St Ives was initially slow to develop due to the perceived remoteness from the city. Settlement increased in the late 1890s, when St Ives was populated by market gardeners, a small dairy, orchard workers and related industries. The suburb since the end of the Second World War has seen its most rapid period of expansion and a steady growth in families moving to the area. Nowadays, St Ives is recognised in the Greater Sydney Region as a relatively safe and wealthy suburb. According to the 2021 Australian Federal Census, St Ives has a median weekly household income of $2,888, well above the state average of $1,829. ==Commercial area==
