On 2 October 2026, three developments altered the resource and procedural conditions governing energy, education-linked migration and immigration enforcement. Chinese refiners reportedly suspended October fuel exports beyond Hong Kong and Macau; Australia commenced new limits on onshore student-visa applications; and the United States Supreme Court agreed to hear a challenge concerning mandatory immigration detention without bond hearings.
China
Reuters reported on 1 October, citing four people briefed on the arrangement, that Chinese refiners had suspended exports of oil products beyond Hong Kong and Macau for October pending further notice from Beijing. The report also said PetroChina had cancelled most of its planned October gasoline and jet-fuel shipments. No publicly issued Chinese government document was cited in the reporting, so the existence, duration and scope of the instruction remain limited to the account attributed to Reuters’ sources.
In a follow-up report on 2 October, Reuters said China’s position as a major supplier of refined fuel in Asia meant that reduced shipments could affect large buyers including Singapore, Malaysia and Australia. Data from energy analytics firm Kpler showed that Singapore was the largest recipient of Chinese gasoline in the first nine months of 2026. Australia was the second-largest importer of Chinese jet fuel and was also among the principal recipients of Chinese diesel. Expectations of fewer exports had pushed Asian gasoline refining margins to a record of more than US$50 a barrel above Brent crude and strengthened near-term prices relative to later deliveries for diesel and jet fuel.
The Australian Government told Reuters that Australia then held petrol stocks equal to 42 days of use, or 110 per cent of the required volume, and jet-fuel stocks equal to 29 days of use, both within normal levels. It said 45 fuel tankers were on their way to Australia and 3.5 billion litres were committed for delivery over the next four weeks. An analyst cited in the report said the direct effect on Australia was limited because most of its diesel came from South Korea, Taiwan, Brunei and Malaysia, although the absence of Chinese barrels reduced the supply available to buyers in the wider market.
Australia
Australia’s Department of Home Affairs changed eligibility for onshore Student and Student Guardian visa applications from 2 October. Most temporary visa holders in Australia can no longer apply onshore for a Student visa, subclass 500, or a Student Guardian visa, subclass 590. Existing Student visa holders are also subject to the new rules when applying for another Student visa. Where the rules prevent an onshore application, the applicant must be outside Australia both when lodging the application and when the visa is granted. Current Student visas are unaffected, and applications lodged before 2 October continue to be assessed under the rules in force when they were submitted.
Home Affairs lists several exceptions for an onshore Student visa application. They include needing no more than 12 additional months to complete the original course with the same provider; sponsorship by the Department of Foreign Affairs and Trade or Defence; applying for a PhD; undertaking primary or secondary schooling; or moving to a course at a higher Australian Qualifications Framework level after completing the main course. Existing Student Guardian visa holders may continue to apply onshore for another Student Guardian visa.
The conditions for including family members have also narrowed. Home Affairs says family members may generally be included where the student is undertaking a PhD, is sponsored by DFAT or Defence, receives a foreign-government scholarship, or is an eligible student from a Pacific country or an ASEAN member state. Family members already included on a current Student visa may be included in a qualifying subsequent onshore application. The primary applicant and all included family members must be in the same location when the application is lodged.
The Australian Broadcasting Corporation separately reported measures directed at migration agents and legal services involved in applications lacking a reasonable factual or legal basis. Current rules allow a registered migration agent to proceed after giving a client written advice that a case is futile. The government proposes to prohibit agents from assisting with an application they know, or reasonably ought to know, has no reasonable basis, and to consult on corresponding accountability for migration lawyers. Home Affairs has also established a dedicated taskforce to investigate unregistered operators who charge for migration assistance. Those agent measures combine an active investigation with proposed or consultative rules; they are distinct from the Student visa limits that commenced on 2 October.
United States
The US Supreme Court agreed on 1 October to hear Rhoney v Barbosa da Cunha, a case challenging the Trump administration’s mandatory immigration-detention policy. The central question is whether non-citizens who have lived in the United States without lawful admission are entitled, after being detained during removal proceedings, to a hearing that determines whether they may be released on bond. The grant of review does not endorse or reject the policy; the case will be considered during the Court’s new term.
The Department of Homeland Security issued guidance in July 2025 treating these non-citizens as “applicants for admission” under federal immigration law, making detention mandatory while removal proceedings continue and excluding access to bond hearings. The interpretation departed from nearly three decades of practice under which non-citizens already living in the country, particularly those without criminal records, could generally seek a bond hearing. The administration says the approach is authorised by a 1996 immigration statute. Lawyers for the challengers argue that it improperly extends a detention rule associated with border arrivals to people arrested within the United States.
The case arose from a challenge brought by Brazilian citizen Ricardo Aparecido Barbosa da Cunha. He entered the United States without permission around 2004 or 2005 and, after immigration officers arrested him in September 2025, was initially denied a bond hearing under the disputed policy. He was later released on bond during a subsequent stage of the proceedings. Federal appeals courts have reached different conclusions: most to consider the issue have held that long-term residents detained inside the country must have access to a bond hearing, while the Fifth and Eighth Circuits have accepted the government’s position. The Supreme Court will resolve that disagreement over the statute’s meaning.
