Despite not commenting directly on strong speculation that online giant Amazon will lease a site at Goodman's Eastern Creek estate in Sydney, Goodman chief executive Greg Goodman said the retail "disrupters are here and the followers are on their way".

"With $8 billion of asset sales over the last three years, we've positioned our business in line with structural changes. We're now looking to the future. We are seeing and we are planning for rapid technology and behavioural changes for both business and consumers as the use of automation and artificial intelligence increases," Mr Goodman said.

"AI in warehouses is accelerating with not just robotics, but data collection where trucks can be sent out at the right traffic times, bar coding to ensure the customer can track the parcels and a more efficient layout internally."

He said although the evolution of e-commerce and supply chain transformation was still at an early stage, "we are seeing increased demand for our expertise in providing high-quality logistics facilities in prime locations. This is a trend we expect to accelerate over the next five to 10 years".

"We are recalibrating the business and see that AI and technology have raised consumer expectations around price, product availability and delivery," Mr Goodman said.

The group has also inked a deal with NSW Ports, the custodian of Port Botany and Port Kembla, to develop NSW Ports' industrial estate at Enfield Intermodal Logistics Centre. It is set on 60 hectares of industrial zoned land on Mainline Road, Strathfield South, Sydney.

"Now while disruptive for some businesses, the early stages of the evolution of e-commerce and supply chain transformations are providing us with opportunities."

The assets sales and a focus on costs has seen Goodman report an operating profit of $776 million, up 8.6 per cent on the 2016 year and operating earnings per share of 43.1??, up 7.5 per cent on the previous corresponding period. The interim dividend of 13.2?? will be paid on August 28.

The results included $1.6 billion of revaluation gains and 14.4 per cent total return from its partnerships and joint ventures. Since 2014, assets under management have grown to $35 billion despite $8 billion in asset sales.

Mr Goodman said he would continue to look at recyling older, non-core land and buildings to apartment developers.

He said the results are supported by the development-led strategy that leverages growing online consumerism in key global gateway cities through Goodman's $3.5 billion workbook. The group has also agreed terms with a partner in Brazil.

"We've taken advantage of the property cycle to make $3.5 billion of asset sales across the platform this financial year, redeployed this capital into strategic developments and reduced group leverage to 5.9 per cent," he said.

"This has provided us with greater financial flexibility and enabled us to improve the quality of our global portfolio by focusing on strategic locations in gateway cities, placing our customers close to their customers."

Analysts said the results were in line with expectations.

According to Peter Zuk from Shaw & Partners, it was another strong result for Goodman, which again benefited from high development margins as well as performance fees in the development and management businesses, offsetting the loss of income from investment property sales.

"Goodman is incredibly well capitalised, with significant reinvestment potential, including $2.1 billion of cash, that should help keep its earnings growth ticking along nice over the medium to long term," Mr Zuk said.

But JP Morgan's Richard Jones said while Goodman is in "good shape", its medium-term challenge is maintaining its earnings growth when yield compression no longer underpins above-trend development margins.

"Goodman has look-through gearing of about 20 per cent and heading lower, plus it has $10 billion of available capacity to fund acquisitions to maintain growth," Mr Jones said.

The share price was down 11?? to $8.43 a security.
