Did you know 81% of Australian women between 16-49 use some form of contraception? But here’s the thing—many of us stick with what we know (usually pills or condoms) without exploring better options! Today’s gold-standard methods such as IUDs and implants offer “set it and forget it” protection that’s over 99% effective.
Whether you want something hormone-free, easily reversible or just plain comfortable, there’s truly something for everyone. This article will walk you through the best contraceptive methods alternatives based on effectiveness, reversibility, discomfort or side-effects, etc.
Types of Contraceptive
In a nutshell, Permanent solutions like tubal ligation and tubal occlusion are suitable for women who do not wish to have more children. Emergency contraceptive methods like the morning-after pill serve as backup options when unprotected intercourse occurs. Each method has unique benefits and limitations, making it essential to consult an obstetrician or a gynaecologist to determine the most appropriate choice.
The Pill (Combined Oral Contraceptives)
What is it: The combined pill contains two hormones, estrogen and progestogen, which work together to prevent pregnancy. It stops the ovaries from releasing an egg each month and makes the mucus at the cervix thicker so sperm cannot get through.
Effectiveness: The combined pill is 99.7% effective when used perfectly but about 91% effective with typical use due to missed pills.
Side-effects or discomfort caused: Side effects may include nausea, headaches, breast tenderness and mood changes, though these often improve after a few months. Some women experience positive effects like lighter periods and reduced acne.
Best suited for: This method suits women who can remember to take a pill daily and don’t have certain health conditions like high blood pressure or a history of blood clots.
Cost: In Australia, the cost ranges from $5 to $30 per month depending on the brand, with many covered by Medicare for around $6.60 per month with a concession card or $41 for three months without concession.
Mini Pill (Progestin-Only Pill)
What is it: The mini pill contains only one hormone, progestogen, which thickens cervical mucus and thins the uterine lining. Unlike the combined pill, it doesn’t always stop ovulation but creates conditions that make pregnancy unlikely.
Effectiveness: With perfect use, the mini pill is 99.7% effective, though typical effectiveness drops to about 91%.
Side-effects or discomfort caused: Side effects are usually milder than the combined pill, but some women experience irregular bleeding, headaches or breast tenderness.
Best suited for: The mini pill is especially suitable for women who cannot take estrogen, including breastfeeding mothers, smokers over 35 and those with certain health conditions.
Cost: In Australia, costs are similar to the combined pill, ranging from $5 to $30 per month, with PBS subsidies available.
IUD (Intrauterine Device) – Hormonal
What is it: The hormonal IUD is a small, T-shaped device inserted into the uterus by a healthcare provider. It releases small amounts of progestogen directly into the uterine lining, making it thinner and cervical mucus thicker.
Effectiveness: This method is 99.8% effective, making it one of the most reliable contraceptives available.
Side-effects or discomfort caused: Some women experience cramping and irregular bleeding in the first few months, but many eventually have lighter periods or no periods at all.
Best suited for: Hormonal IUDs are ideal for women seeking long-term, highly effective contraception without daily maintenance.
Cost: IUDs work for 5 years and cost between $200 and $400 for insertion in Australia, though Medicare rebates can reduce this significantly and the Mirena IUD is available on PBS for around $6.60 with a concession card or $41 without.
IUD (Copper)
What is it: The copper IUD is a non-hormonal alternative that uses copper’s natural spermicidal properties. The copper creates an environment in which sperm cannot survive and affects the lining of the uterus to prevent a fertilized egg from implanting.
Effectiveness: Copper IUDs are 99.4% effective and can work for 5 to 10 years, depending on the type.
Side-effects or discomfort caused: Side effects often include heavier periods and more cramping, especially in the first few months after insertion.
Best suited for: This option is excellent for women who prefer non-hormonal contraception or cannot use hormonal methods.
Cost: In Australia, copper IUDs cost between $80 and $150 for the device, plus insertion fees of $70 to $300, with partial Medicare rebates available for insertion.
Implant (Nexplanon)
What is it: The contraceptive implant is a flexible rod about the size of a matchstick inserted under the skin of the upper arm. It continuously releases progestogen to prevent ovulation and thicken cervical mucus.
Effectiveness: With 99.95% effectiveness, the implant is one of the most reliable methods available.
Side-effects or discomfort caused: Side effects commonly include irregular bleeding patterns, with some women experiencing frequent or prolonged bleeding while others have fewer or no periods.
Best suited for: The implant is particularly suitable for women who want long-term protection without daily attention.
Cost: Implant lasts for up to three years and costs around $40 with a Medicare card in Australia, including both the device and insertion procedure.
Injection (Depo-Provera)
What is it: The contraceptive injection delivers a dose of progestogen that prevents ovulation, thickens cervical mucus and thins the uterine lining. Each injection provides protection for 12 weeks.
Effectiveness: This method is 99.8% effective with perfect use, dropping to about 94% with typical use.
Side-effects or discomfort caused: Side effects may include weight gain, headaches, mood changes and irregular bleeding, with some women experiencing no periods after several injections.
Best suited for: The injection suits women who want medium-term contraception without daily attention.
Cost: In Australia, each injection costs between $30 and $40, with Medicare rebates available, bringing the price down to around $6.60 with a concession card.
Sterilisation (Tubal Ligation)
What is it: Tubal ligation is a surgical procedure that blocks or cuts the fallopian tubes, preventing eggs from travelling from the ovaries to the uterus. This stops sperm from reaching an egg for fertilization.
Effectiveness: The procedure is over 99.5% effective and is considered permanent.
Side-effects or discomfort caused: Recovery involves minor discomfort for a few days, with most women returning to normal activities within a week.
Best suited for: Sterilisation is appropriate for women who are certain they don’t want more children.
Cost: In Australia, the procedure costs between $2,500 and $6,000, though Medicare covers most of this in public hospitals, with out-of-pocket expenses typically between $80 and $500.
Vaginal Ring (NuvaRing)
What is it: The vaginal ring is a flexible, transparent ring inserted into the vagina that releases estrogen and progestogen. It remains in place for three weeks, followed by a ring-free week, during which a period usually occurs.
Effectiveness: When used correctly, the vaginal ring is 99.7% effective, though typical use brings this down to about 91%.
Side-effects or discomfort caused: Side effects are similar to the combined pill and may include headaches, nausea, breast tenderness or vaginal irritation.
Best suited for: The ring is ideal for women who want monthly rather than daily contraception and don’t have contraindications to oestrogen.
Cost: In Australia, it costs approximately $25 to $30 per month without a PBS subsidy, as it is not currently covered by the PBS.
