BIO: Lachlan Olbrich was born in Adelaide (SA) and attended Reynella East College. He began playing basketball as a junior with the Southern basketball program and represented SA Metro in both 2020 and 2021 National Championships. He was also a part of South Australia’s state squad at the 2021 U20’s National Championships. There he led the team to a bronze medal, led the event in steals per game (2.4) and was third in overall rebounds (8.8 per game).

NBL EXPERIENCE

Lachlan Olbrich made his NBL debut with the Adelaide 36ers at 18 years of age. He went scoreless in his first NBL game.

Adelaide made several key additions for the season, including Mitch McCarron, Kai Sotto, and imports Dusty Hannahs and Todd Withers. The team also replaced coach Connor Henry with CJ Bruton just weeks before the season began. Bruton added Hyrum Harris and Cam Bairstow, with the latter looking to revive his career after injury-plagued seasons.

Mitch McCarron was named team captain, and Adelaide started the season with a mixed performance, securing early wins against Tasmania and New Zealand after losing to Perth and Illawarra. However, the team’s fortunes quickly declined when Isaac Humphries was sidelined with a season-ending knee injury after just six games. Cam Bairstow stepped up in Humphries’ absence but also suffered an injury later in the season.

Adelaide struggled to find consistency, and with disappointing seasons from imports Dusty Hannahs and Todd Withers, they were out of playoff contention early, finishing the season in seventh place with a 10-18 record. Daniel Johnson led the team in scoring, while Sunday Dech and Hyrum Harris showed improvement.

As a development player, Lachlan Olbrich saw limited action, appearing in only three games without scoring.

ILLAWARRA HAWKS

Following the worst season in club history, Illawarra entered Jacob Jackomas’ second year as head coach after Tim Coenraad and Kevin White retired, while Akoldah Gak (to Cairns), Mangok Mathiang (to New Zealand), Alex Mudronja (to Cairns), Michael Frazier II, Peyton Siva, Lachie Dent and Deng Deng exited.

Olbrich (3.8 points and 3.1 rebounds across 31 games) joined Illawarra on a three-year deal after one season at UC Riverside, where a 19-point and 10-rebound performance against the Hawks during their previous preseason placed him firmly on the club’s radar. Hawks GM of Basketball Mat Campbell said, “He has great size and length, and we love his aggressiveness. We were looking to add some front-court depth to the roster.” Before the NBL season began, Olbrich helped West Adelaide win the 2023 NBL1 Central championship and was named Grand Final MVP after producing 24 points, 10 rebounds, 8 assists and 1 block in the 106-95 win over Forestville.

His first major performance came against South East Melbourne on October 7, where Olbrich (11 points, 4 rebounds, 1 assist, and 1 block) made 5-of-6 from the field in 16:02 as Illawarra defeated the Phoenix 113-106 and collected its first win of the season.

Swaka Lo Buluk was also named the Hawks’ Defensive Player of the Year, while Grida received the Players’ Player and Community awards as Illawarra increased its scoring from 80.8 to 91.6 points per game.

Illawarra opened the postseason against Tasmania at MyState Bank Arena, where Olbrich (2 points, 3 rebounds, and 1 assist) played 11:23 off the bench.

At the NBL Blitz, Olbrich (17 points, 5 rebounds, 2 assists, and 3 steals) helped Illawarra defeat South East Melbourne 112-93 before scoring 29 points in a 106-100 loss to Melbourne, placing his name on the radar of the NBA scouts in attendance.

Illawarra opened the regular season at HoopsFest on September 21 with a 102-75 win over Cairns, where Olbrich (12 points, 11 rebounds, and 3 assists) produced his best all-round game of the regular season during 20 minutes off the bench, with Days (20 points, 12 rebounds, and 2 steals) and Froling (19 points, 8 rebounds, and 1 block) leading the Hawks while Tanner Groves (19 points, 7 rebounds, and 1 block) was Cairns’ best.
