The 13th Australia New Zealand Conference on Geomechanics was organised by the Australian Geomechanics Society (AGS) and held in Perth, Western Australia, at the Perth Convention and Exhibition Centre between 1 and 3 April 2019. The current ANZ series of conferences on geomechanics is held under the auspices of the ISSMGE and started in 1971 (noting that five ANZ conferences on soil mechanics and foundation engineering were held between 1952 and 1967). Previous events in the current series were held in Melbourne (1971), Brisbane (1975), Wellington (1980), Perth (1984), Sydney (1988), Christchurch (1992), Adelaide (1996), Hobart (1999), Auckland (2004), Brisbane (2007), Melbourne (2012) and Wellington (2015). The cooperation of the sister New Zealand Geotechnical Society (NZGS) is acknowledged.

2.1 Abstracts and papers
A total of 369 abstracts were submitted and peer reviewed, resulting in 199 papers in the proceedings volume. The host country led the submissions as shown in Figure 1. It is interesting to note that 10.4% of final papers came from 13 countries belonging to other regions of the ISSMGE.
The distribution of papers by the main themes of the parallel sessions is presented in Figure 2.

Each winner received a certificate and A$1,000 and the highly commended finalists received a certificate and A$500.
3. Social program
A pre-conference field trip showcasing Perth’s regional geology highlights was organised. The tour went to the rugged Darling Range to the East of Perth and visited Canning Dam, its quarry and the surrounds. Then it returned to the centre of Perth for lunch at the iconic Old Swan Brewery. After lunch the tour head to the magnificent Indian Ocean Coastline with its coastal limestones in Fremantle at the Fremantle Port, historic Round House and Whalers Tunnel. From Fremantle the tour returned to the Perth CBD.
The conference gala dinner was held at Fraser’s in Kings Park, the state’s reception centre that celebrates the best Western Australia has to offer in food and wine. The event included entertainment from Domenic Zurzolo, one of Australia’s premier guitarist, and Mick Collis (author, poet and rugby commentator) with a fascinating story of how it took him ‘42 years to play for Australia’.

4. Conference attendance
A total of 465 delegates (including exhibitors and sponsors) attended the conference (Figure 6). The distribution by country of origin is presented in Figure 7, noting that apart from Australia and New Zealand, 20 other countries were represented.
A total of eight plenary sessions were held, including seven keynotes and a panel discussion organised by the ISSMGE’s Corporate Associates Presidential Group on the topic of ‘Collaboration in geotechnical engineering – Impact on Research and Project Delivery’. A total of 179 papers were presented in 40 parallel sessions. The technical program was complemented with 20 electronic poster presentations.

The exhibition space was sold-out to accommodate 43 booths for sponsors and exhibitors. Two prizes of A$500 were drawn among attendees that completed a delegate passport by visiting several stands.
6. Venue for next ANZ Conference on Geomechanics
Hosting of the ANZ Conference on Geomechanics rotates 2:1 between Australia and New Zealand. The AGS will host the 14th ANZ Conference on Geomechanics in Cairns, Queensland in 2023.
