However, when he landed at Perth, 2.5kg of powder was found in the bag, 2kg of which was cocaine, estimated to be worth between $700,000 and $1.4 million.
Border Force officer Christopher Brown told the court Arbon had claimed he was trying to organise a loan of $US120,000 with a Nigerian man named "Doctor William Johnson" who had approached him via the internet, ABC reported.
Arbon said he had intended to sign some loan documents in India, but told a Border Force officer he was to meet "Dr Johnson" in Sydney for this.
The Border Force officer said Arbon told him of a previous occasion when he brought two suitcases from India to Perth, to be collected by two men of Indian descent.
Arbon's defence lawyer, Sarah Oliver, said he had fallen victim to online scammers.
He was an "innocent victim of a criminal enterprise who targeted him on-line".
Arbon was a "good person" who did not know he was involved in trafficking drugs, Ms Oliver said.
Prosecutor Edward Fitzpatrick cautioned the jury against having sympathy or prejudice for Arbon, despite the fact he "seems a rather grandfatherly man".
